Contax G1
In the early 1990's, Kyocera introduced an apparent oddity: a new line of interchangeable-lens rangefinder cameras that did not use the established Leica-M or Leica-screw lens mounts. The new camera, the G1, used the "G"-mount, an electronic autofocus mount. Leicaphile detractors were quick to accuse the camera of not being a "true" rangefinder, since it used autofocus. But the AF mechanism in the G1, and later the G2, does indeed use a twin-window system much like that of the older mechanical rangefinders--only in electronic form.
The lenses made by Zeiss for the G-series quickly established it as a camera of worth: the original 45mm f/2 planar was joined by a 28mm f/2.8 biogon and a 90mm f/2.8 sonnar; a 21 f/2.8 biogon and a 35mm f/2 planar were added later. The 45mm Planar in particular gained renown as the sharpest 35mm camera lens ever tested by the Swedish test site [Photodo] -- outclassing even the illustrious Leica 50mm Summicron.
